The combination of isocyanates or thioisocyanates with anilines are expected to result in reactions similar to those between isocyanates with amines. We provide the following as examples:
Isocyanates polymerize readily, particularly with amines (Richter, R.H., R.D. Priester Jr. 2000. Isocyanates, Organic. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc.).
Triethylphosphine may cause polymerization of isocyanates (Pohanish, Richard P.; Greene, Stanley A. (2009). Wiley Guide to Chemical Incompatibilities (3rd Edition). John Wiley & Sons).
Isocyanates undergo violent, rapid reactions with amines (Pohanish, Richard P.; Greene, Stanley A. (2009). Wiley Guide to Chemical Incompatibilities (3rd Edition). John Wiley & Sons).
